Hafnium is a chemical element with the symbol Hf and atomic number 72. Here are some interesting facts:

  • It was discovered and first isolated by Dirk Coster and George de Hevesy in 1922.
  • It is  a lustrous, silvery gray, tetravalent transition metal.
  • It chemically resembles zirconium and is found in many zirconium minerals. 
  • Hafnium is named after Hafnia, the Latin name for Copenhagen, where it was discovered.
  • The mixed carbide tantalum hafnium carbide (Ta4HfC5) possesses the highest melting point of any currently known compound, 4,263 K (3,990 °C; 7,214 °F). Recent supercomputer simulations suggest a hafnium alloy with a melting point of 4,400 K.
  • The low abundance and difficult separation techniques necessary make it a scarce commodity.
